Epigenetic Modification Mediates the Increase of LAG-3


PMID 28028751

Abstract

Immune suppression plays critical roles in the development of chronic osteomyelitis, and the mechanisms underlying the development of immune suppression in chronic osteomyelitis have attracted much attention. LAG-3 is an important suppressor of T cell activation, but the role of LAG-3 in the immune regulation of chronic osteomyelitis is currently unknown. We sought to demonstrate if LAG-3 plays crucial roles in chronic osteomyelitis progression and has effects on immune suppression and exhausting of T cells, and what is the mechanism underlying LAG-3 deregulation in chronic osteomyelitis. We examined the expression of LAG-3 in the T cells of peripheral blood of 50 healthy controls and 50 patients with chronic osteomyelitis by flow cytometry. Clinical data were analyzed to determine the correlation between inflammation index and LAG-3 expression. Moreover, we isolated the CD4
